White matter hyperintensity (WMH) metrics by exposure group and ApoE promoter genotypes. There are no significant differences by any of the three observed genotypes at rs405509 (top) for individual groups or the cohort as a whole (total cohort). Neither are there any significant associations observed at rs769446 (bottom). Error bars represent standard deviation from the mean; sample sizes are indicated as italicized numbers beneath the respective bar
